Yuav ua li cas xaiv magnesium cib thiab siab aluminium cib
Magnesium bricks belongs rau MgO cov khoom yog alkaline refractory cib, vim li cas koj hais li ntawd? Nws yog vim hais tias magnesium oxide yog ib qho alkaline oxide, uas muaj qhov sib xws ntawm alkaline oxide thiab yog cov khoom siv gelling. Cov hmoov dawb los yog dawb dawb, tsis muaj ntxhiab, tsis qab, tsis muaj tshuaj lom, yog ib qho alkaline ntiaj teb hlau oxide, tshuaj formula MgO. Lub melting point yog 2852 ° C, lub boiling point yog 3600 ° C, thiab qhov ceev yog 3.58g / cm3 (25 ° C).
Cov khoom siv raw rau kev tsim cov magnesia bricks feem ntau yog nyob ntawm magnesite, thiab cov txheej txheem tsim cov magnesia bricks yog sib tov cov hlau nplaum tuag (cov khoom qis dua 5 hli rau cov hmoov zoo) nrog rau qhov tsim nyog ntawm sulfite pulp khib nyiab kua lossis caustic magnesia ua binder nyob rau hauv xovxwm molding.
